Importance of wall behind listener?


In my audio setup, I essentially have no back walls to speak of. Behind the listener is an opening into a long hallway, an opening to a den (to the left of listening position), and an opening to the kitchen (to the right of listening position). I'm wondering if this is a hinderence in getting a truly 3D holographic soundstage representation. Other folks who have a near identical systems get phenominal soundstages, so I know it's not any of the equipment. The difference is they have a back wall vs. my no back wall, and their straight ceiling vs. my sloped celiling (peaked at center, dropping on both sides).

Any thoughts?

I also have a similar configuration, but with a 9" flat ceiling a 12'rear opening in the center of the rear wall (an entry/foyer followed by a 12' hallway). I found that a Janis 15" Subwoofer placed in the rear corner added a significant demensional improvement.
This unit is upward fired, and has a variable output. But once you have it set it blends very well.I have no experience with diffusion or other sound treatments. Other responces are very positve, but I am concerned cosmetics.
